Position-Time:
As the line slopes upward, positively, the position of the object is moving forward farther away from the starting point. The greater the slope the faster the object is moving from the starting point. A negative slope indicates that the object is moving back toward its starting point. A greater negative slope means that the object is moving toward its starting point at a greater speed. When the line has a zero slope the object has stopped. When the line crosses the x-axis, the object has passed the starting point. This did not happen during our lab investigation because if we were to pass the starting point, the motion sensor would not be able to measure the position.
Velocity-Time:
A line sloping upward on the velocity-time graph indicates that the object is gaining speed. If the line becomes parallel to the x-axis, the object has came to a constant speed. When the line has a negative slope, the object is slowing down. If the line crosses below the x-axis, the object has a negative velocity and is moving backward. The greater the slope of the line the faster the object is moving.
